This filter kit includes three filters - the long pre and post filters, and the shorter formulation cartridge which adjusts the TDS of your final product water.  These filters will fit the Cirqua HP800 perfectly, match the original equipment specs, and are of equal or better quality than the original equipment.  In stock and ready to ship today!  

If you need only the formulation cartridge, try our Cirqua HP800 Formulation Cartridge.
